        <h1>Example: Listening For Menu Events (YUI Library) <em>[<a href="index.html">Examples Home</a>]</em></h1>
        <p>This example demonstrates how to listen for DOM-related events.  Interaction with the Menu will result in event information being output to the console.  <em>Please note</em>: Disabled MenuItem instances do not fire DOM events.  This is demonstrated with the MenuItem named "MenuItem 2."</p>
        <p id="clicknote"><em>Note:</em> By default clicking outside of a menu will hide it.  Additionally, menu items without a submenu or a URL to navigate will hide their parent menu when clicked.  Click the "Show Menu" button below to make the menu visible if it is hidden.</p>
        <button id="menutoggle">Show Menu</button>
